COMBINED PHONOGRAPH AND RADIO RECEIVING APPARATUS.

Application filed. June 23, 1924. Serial No. 721,709.

This invention relates to a combination phonograph and radio receiving apparatus and it is the object of my invention to provide such an apparatus which may employ a single amplifying horn, which horn may be connected to either the phonograph or the radio apparatus, at will.

,.,More specifically the object of my invention is to provide a combined phonograph and radio receiving apparatus having a common amplifying horn'and having a pivoted neck for the horn which may be adjusted so as to, register with the tone-arm of the phor 1- ograph, or with the arm leading to the radio loud speaker.

Other objects will be in part apparent and in part pointed out during the progress of the description. 1

In the drawings in which ll have illustrated a preferred embodiment of my invention,

Fig. 1 is a front elevation of a portion of a cabinet containing my apparatus.

Fig. 2 is a vertical section through a portion of the cabinet.

Fig. 3 is a section on the line 3-3 of Fig.

' 2, and Fig. 4: is a section on the line 44 of Fig. 2.

Referrin now to the drawings, 1 designates .a ca inet of any suitable form containing a phonograph and a radio receiving set. This cabinet may take the form shown in my copending application, Serial No. 713,128, filed May 14: 192 1, or it may be of any other form desired. The phonograph comprises the usual turn-table 2, reproducer 3 and tone-arm 4 mounted on a motor-board 5. The radio-receiving set is indicated generally at 6 and may be of any type desired. The loud speaker for the set is indicated at 7 and, of course, is connected to the set 6 by a suitable conductor 8. Extending towards the front of the cabinet is an amplifying horn 9, the bell mouth of which is received in a block 10, which forms in effect a portion of the horn.

In the normal operation of a 1phonogpaph sounds are transmitted throng the tonearm and through a suitable neck connecting the tone-arm to the block 10, and thence through the block 10 to the horn 9, as is well known in the art.

On the under side of the motor-board 5 I provide an element 11 having hollow arms tends to the radio loud speaker 7 whereby sounds may be transmitted from the receiver through said arm 13. The under side of the element 11 is preferably made'with an arc'uate surface 15, the center of which is at the center of the pins 16. The element 11 is rigidly secured to the block 10 by means of a framework 17 fastened to the block 10, as by screws 18, and to the element 11 as-by bolts 19.

The framework 17 is provided with a coliar 20- in which is received the enlarged end 21 of a hollow neck 22. The neck 22 is pivoted 0a the pins 16, as will be evident from an inspection of Figs. 2 and 4. The ins 16 are set in lugs 16 on the framework 1 The I end 21 of the neck 22 is out on a bias both ways from the center, as shown in Fig. -2, whereby rotation about the pins 16 is permitted.

The upper endof the neck 22-is provided with an arcuate extension 23 adapted to contact with the surface 15, and the wall of the neck 22 is flanged, as at 24:, to provide a bearing against said surface 15.. At a point on the neck 22 adjacent to the upper end thereof is provided a lug 24: in which slides a pin 25 carrying a brake '26, also of arcuate surface, to contact with the. surface-15. The brake 26 is held in yielding engagement with the-surface 15 by means of the spring 27.

Movement of the neck 22 about the pins 16- to bring the neck 22 into the position shownin Fig. 2, and it is evident that the neck 'will be yieldingly held in this position by the brake 26 andthat the sounds from the phonograph will be transmitted through the tone-arm 4., arm 12, neck 22 and block with the portion of the framework fastened to the block 10. If it is desired to modify the volume of sound coming from either the phonograph or the radio,-it is possible to do so by a movement of-the rod 28 to cause a partial movement of the neck 22 and to cut off a portion of the sound transmitted thereto.

From the above it will be seen that Ihave provided a combined phonograph and radio receiving apparatus employing a common horn and also having a common neck for the horn, which is adjustable to either of two positions to serve in effect as a switch from the phonograph to the radio loud speaker, or vice versa.

I am aware that changes in the form, con- I struction and arrangementof parts may be madewithout departing from the spirit and "without sacrificing the advantages of the invention and I reserve the right to make all such changes as fairly fall within the scope of the following claims.

1. Ina device of the character described, a phonograph, a radio loud speaker, a fixed amplifying horn, and a pivoted neck adapted to connect said amplifying horn to either said phonograph or said loud speaker.

2. In a device of the character described, a phonograph, a radio loud speaker, a fixed amplifying horn, a pivotally movable neck adapted to connect said amplifying horn to either said phonograph or said loud speaker, and means for limiting the movement of said neck, I

3. In a device of the character described, a phonograph, a, radio loud speaker, an amplifying horn, a pivoted neck adapted to connect said amplifying horn to either said phonograph or said loud speaker, and a brake associated with saidneck to yieldingly hold it in its adjusted position.

4:. In a device of the character described, a phonograph, a radio loud speaker, a fixed amplifying horn, a pivoted neck adapted to connect said amplifying horn to either said phonograph or said loud speaker, a cabinet containing said elements, and means operable from the outside of said cabinet to operate said neck.

5.'In a device of the character described, a fixed amplifying horn, a phonograph, a radio loud speaker, and a neck pivoted to said horn and adopted to be brought into neath said motor-board and comprising two arms, one registering with said tone-arm i and the other adapted to be eonnected to a radio loud speaker, a fixed amplifying horn,

and a neck pivoted to said'hozgn and adapted to register with either of the arms of said element.

7. In a device of the character described, a cabinet having a motor-board, a tone-arm mounted thereon, an element mounted beneath said motor-board and comprising two arms, one registering with said tone-arm and the other adapted to beconnected to a radio loud speaker, an amplifying horn, a neck pivoted ta said horn and adapted to register with either of the arms of said element, and a yieldable brake to hold said neck in adjusted position.
